摘要：

The deployable antenna mechanism is a key component of the mesh deployable antenna,which has a significant influence on the stability and stiffness of the structure after deployment.A new configuration of radiating rib space deployable antenna mechanism was designed to address the development trend of large scale,high storage rate, and high accuracy of space deployable antennas.Firstly,the overall structural design of the antenna was designed,and a three-dimensional model of the structure was established based on the dimensional calculation of the structural composition.Then,the kinematic simulation study of the mechanism was carried out by using numerical simulation software,and the variation law of the motion was analyzed.Finally,a finite element model was established,and the structural modal analysis was carried out.The results show that the proposed mechanism can realize the motion change from folded state to deployed state,and that the mechanism has good synchronization during the deployment process without interference between the components,which verifies the correctness and feasibility of the structural scheme and principle.The research results can provide a reference for research on the basic theory of a deployable antenna mechanism and related engineering applications.
